B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 5" Channel size, Plain, Grip Strut, 10 gauge

Yes. The five diamond Grip Strut plank is listed as OSHA compliant and is intended to give safe, sturdy footing where a non-slip walking surface is required, which is what makes it common on mechanical platforms, catwalks and stair treads.

The plank is 10 gauge steel with a plain finish, meaning bare, uncoated steel. Indoors or in a dry mechanical room that is fine as-is. Outdoors or in a washdown or corrosive area it will rust, so either field-coat it or specify a galvanized version instead.

Each 120 inch plank weighs 17.5 pounds, so one man can carry and set a section without a lift. That dead load figure is also what you add per plank when checking an existing platform frame.

Diamond count refers to how many rows of pierced, serrated diamonds run across the walking surface, which sets the width. The five diamond version gives an 11.75 inch wide surface on a 5 inch deep channel, so it is used for walkways and platform decking. Narrower two or three diamond pieces are the ones you use for stair treads and single-plank runs.

At 10 gauge, this plank is the heavier of the common Grip Strut thicknesses and is the usual pick for plant and utility walkways with regular foot traffic and tool carts. Lighter gauges are meant for lower traffic access platforms. The 5 inch channel depth is what carries the span, so set your support spacing to the load you expect.
